Improvement in water-wheels



UNITED STATES PATENT, OEEICE.,

W'ILLIAM SIMPSON AND HORACE ADAMS, lOF LANGDON, NEWY HAMPSHIRE,

||v| PRovEM ENT lN WATER-WH EELS.V

Specification forming part of Letters Patent No. 5,312, dated October'2, 1847.

To all whom t may concern: Be it known that-we, WILLIAM SIMPSON and HORACE ADAMS, of Langdon, in `the 'county of Sullivan and State of New Hampshire, have invented a new and u'seful Method of Constructing a Water-Vheel, its form being such as to receive the combined percutieut, centrifugal, and reactive forces of the Water when applied to it, and which is denominated Simpson &Adams CombinedWater-Wheeh? and we hereby declare that the following is a full and exact description thereof, reference being had to the annexed drawings.

Figure l is aperspective view of the wheel. Fig. 2 is a plan view of the wheel, encircled by the platform beneath which it runs, and also a vertical sectional view of the ajutage for introducing the water and of the cylinder for retaining it within the circumferenceof the wheel. Fig. 3 isa perspective view of the platform, aj utage, and cylinder, with the wheel in its plane beneath it.

Fig. l, the perspective view, shows the Wheel upon the shaft A, and which consists of a plate B B of cast-iron or other material, with a lip O attheperipheryprojectingfromits upperdisk, and three or more curved tapering channels D D D (see also sameletters, Fig. 2) sunken in the plate, the small en ds of which commence about one-third of the distance from the center to the periphery, and on a line with the circumference at that point, and from thence diverging, widening, and becoming deeper until they have gained half around the center and nearly to the periphery of the plate, where they constitute the openings E E for the discharge of the Water.

upper disk of the plate there are a corresponding number of buckets F F F, extending along within the periphery and across that part of the plate at the discharge e'nds of the channels D, Figs. l and 2.

Projecting from the ery and encircling the buckets upon the upf per surface of the Wheel. H H shows a Vertical sectional view of the ajutage for introducing the water to the wheel, and also of the cylinder or-case Il for retaining it upon the wheel until it has passed through the discharges E E.

Fig. 3 is aperspective view of the platform Gr G and the ajutage H H, and. of the cylinder I, with the wheelin its place .beneath it.

Operation: The water is introduced froma bulk-head through the ajutage H H, when it operates; first, by percussion upon the buckets, and, being retained upon that part of the Wheel within the buckets along the periphery, it becomes a continuous resistance for the water from the ajutage to drive against. By thus introducing the water a head is immediately formed within the cylinder, and which acts, secondly, as a whirlpool by its pressure and centrifugal force' against the bot-toms and outer edges of the channels DD, and, thirdly,

by its reactive force as it passes from the forth.
